Neon Engine vs CX Music Player

Transform your music into a sound that feels uniquely yours. Neon Engine is an on-device audio workshop for reshaping local music with immersive effects. Import a track, preview different styles, fine-tune the result, and save it to your personal library—all directly on your iPhone. -- AUDIO MODES -- Bass Enhance: Add more weight and depth to your music with a stronger low-end sound. Slowed + Reverb: Adjust the tempo, tone, and reverb to create a deeper, more atmospheric mix. City Pop: Give your track a bright, nostalgic character inspired by retro nighttime soundscapes. Fast Tempo: Speed up your music with adjustable tempo controls, from a subtle lift to a high-energy remix. Original: Save and manage the original track alongside your converted versions. -- BUILT FOR YOUR MUSIC -- Live Preview: Hear each effect before saving and fine-tune supported modes in real time. Personal Library: Organize converted tracks, rename them, filter by effect, and mark favorites for quick access. Bulk Actions: Select multiple tracks to update favorites or delete them together. Files Integration: Import compatible audio files directly from the iOS Files app. Background Playback: Continue listening to tracks from your Neon Engine library outside the app. -- PRIVATE BY DESIGN -- Your music stays on your device. Audio processing is performed locally without uploading your files to a remote server. Neon Engine is designed for local audio files you own and for personal, creative use.

CX Music Player is a simple, free music player for audio files you already keep in Files. Choose a folder, review the music found inside it, skip subfolders that contain podcasts or sound effects, and import only the tracks you want. After import, it reads common MP3 ID3, M4A/MP4 atoms, and FLAC/Vorbis tags locally on your device. Compatible local M3U8 playlists can keep your chosen order.

Audio, filenames, embedded tags, cover art, imported M3U8 data, Library data, Finds, and Plans are processed locally. A shared planning JSON contains metadata, notes, public source links, and portable IDs—not audio, local file paths, or API keys—and goes only to the iOS destination you choose. Current output names and types are displayed only in memory. Imported audio and its cover art are marked excluded from device backups; iOS may back up small non-audio app data. GOOD TO KNOW iOS does not let apps silently scan the whole phone. CX Music Player scans only the Files folder you explicitly choose. M3U8 playlists may reference only relative files inside that folder; web addresses and other arbitrary URIs are not loaded. The app does not access Apple Music or MusicKit, stream music, download from media services, or share your audio files. Importing creates a local copy and therefore uses device storage. Direct MusicBrainz and Last.fm search is disabled in this release pending terms and privacy review. Optional Google and YouTube actions open a fixed search in Safari; CX Music Player does not scrape results, embed those sites, or download media. Driving Mode is an in-app screen, not a CarPlay app. CX Music Player cannot pair a radio, force a Bluetooth connection, change the radio source or priority, or configure automatic reconnection. Pair and configure your car through iPhone Settings and the radio while parked. Supported file extensions: MP3, M4A, AAC, WAV, AIFF, AIF, CAF, and FLAC. Playback depends on the file's codec and integrity. Playlist format: UTF-8 M3U8 with local relative paths. Choose your folder and press play. That's it.
